Original application filed March 8, 1923, Serial No. 623,646. Divided and this application filed February 14, 1924. Serial No. 692,669.

This invention relates to creel's or racks of the character used to support spools,

cops, or other thread bodies from which thread is drawn in warp beaming and similar operations The invention is especially concerned with the construction and mounting of the holders which support the thread bodies. 7 I

It is the general object of the invention to devise a construction of this character which can be manufactured economically and which will be more satisfactory in op-v eration than prior constructions. The invention aims particularly to eliminate the vibration of the thread body as it rotates during the unwinding of the thread therefrom and which has proved very objectionable heretofore, especially in unwinding thread from an open wound thread package.

The nature of the invention will be readily understood from the following description when read in connection with the accompanying drawings, and the novel features will be particularly pointed out in the appended claims.

Referring now to the drawings Figure l is aside elevation, partly in cross section, showing a thread body holder and the supporting means therefor with the thread body mounted on said holder;

, Fig. 2 is a cross sectional View of a portion of the holder and its support on a larger scale; and

Fig. 3 is a View of the more important parts shown in Fig. 1, but showing a thread body supported on the holder in a different manner.

In the construction shown the holder for the thread body consists of a pin 2. This pin is supported in a rail 3 of channel section, the pin projecting through the opposite flanges or webs of the rail. A bracket 4 supports a series of these rails, and for this purpose is provided with steps, one of which is shown at 5, the rail being secured on the step by a bolt 6; Interposed between the step and the rail is a wedgeshaped block 7 through which the bolt 6 projects, this block serving to tip the rail sufiiciently to give the pin ,2 the inclination desired to keep the thread body from slilpping olf it. The holes in the flanges of t e rail through which the pin projects are thread bodyconsisting of a S carrymg a quantity of thread T. This manner of supporting the thread body on tween the collar 8 and therail 8 to coop crate with the stops in limiting the endwise movement of the pin 2.

Fig. 1 showsthe holder 2 spool or core the pin 2 is satisfactory where the thread is wound on the core or spool in the usual manner; but when an open wound thread package is used, the unwinding operation causes the thread to traverse rapidly from one end of the thread package or body to the other, and this rapid traversing move I ment is very likely to produce an objectionable vibration of the entire thread body. I have found that this vibration is eliminated by mounting the thread body holder, as above describechso that it can have a limited endwise ,move nent. qualities of an open wound thread package, also, are improved by mounting the thread package as shown in Fig; 3 sothat it bears at one'end on the shouldered portion of the collar 8, andat its other end on the pin 2 which is considerably smaller indiameter than the part 10. lVhile I prefer to make use of both the endwise movement of the pin and the two diameters support for the thread package, either of these features may be used without the other. The exact reason for the improved results produced by mounting the thread body on a holder presenting two diameters for its support, as shown in Fig. 3, are not entirely clear, still I have found in actual practice that this arrangement does produce superior results in using thread packages of the open wind type.

It will be evident that the construction provided by this invention can be manufactured very economically, and that it is very adaptable to different sizes and arrangements of creels. The arrangement for supporting the rail 3 permits the use of the reduced or shouldered porsupporting a p The running same parts, While gh'ing the desired inclination to the pins, Whether the bracket is mounted in an upright or inverted position.

The present application is a division of my prior application, Serial No. 623,6 l6, tiled March 8, 1923.

Vt hile I have herein shown and described the best embodiment of my invention that I have so far devised, I do not ish to be limited to the exact details of the construction shown.

Having thus described my invention, what I desire to claim as new is 1. In a creel of the character described, the combination of a pin for supporting a thread body, and a rail in which said pin is mounted for free limited movement transversely of the rail.

2. In a creel of the character described, the combination of a holder for a thread body comprising a pin having an enlarged shoulder at the base thereof to support a portion of a thread body, a rail in which said pin is mounted for free movement in a direction axially ot' the pin, and stops for limiting said axial movement.

3. In a creel of the character described, the combination of a pin for supporting a thread body, a rail holding said pin in a position slightly inclined With reference to a horizontal plane, said pin projecting loosely through said rail whereby it may move endwise relatively to said rail, and sto )S on the pin for limiting said endwise movement.

4. In a creel of the character described, the combination of a pin for supporting a thread body, a rail in which said pin is mounted, a bracket supporting said rail, a Wedge-shaped block interposed between said rail and bracket, and means for securing said rail to the bracket, said block serving to tip the rail slightly to cause it to hold said pin in an inclined position.
